Description

Technical Field

[0001] The invention relates to the technical field of anchor windlass buffering, and in particular to a buffering structure, an anchor windlass based on the structure and a use method thereof. Background Art

[0002] A machine used on board to raise and lower anchors and anchor chains. It uses human power, steam engines, electric motors, hydraulic motors, etc. as power. It is usually installed on the forecastle deck of the ship. Its development trend is to use one unit to achieve operations such as anchoring, mooring, automatic mooring and cable-carrying. According to the drive form, it can be divided into: manual, electric, and hydraulic. The windlass is mainly composed of a base, a bracket, an anchor chain wheel, a brake, a sprocket, a gearbox, an electronic control system (except for the manual windlass), etc. The electric windlass has an electric motor, and the hydraulic windlass has a hydraulic pump station; Chinese patent CN215883980U discloses a conveniently fixed marine anchor windlass auxiliary device. Through the buffer protection mechanism, the mounting base plate can be mounted on the outside of the linkage shaft, and the mounting position and number of the mounting base plate and the buffer plate can be adjusted. Then, water is added into the buffer bin from the water inlet pipe, so that the buffer plate is buffered by the water, thereby improving the buffer braking protection of the linkage shaft rotation, facilitating the buffer braking of the anchor chain when it is lowered, facilitating the buffer braking of the chain when the marine anchor windlass is used, and also facilitating the adjustment of the buffer braking degree of the marine anchor windlass chain.

[0003] When the anchor is lowered, the anchor will quickly drive the anchor chain on the anchor chain roller to fall due to its own weight and inertia. When the anchor hits the bottom of the water quickly, the impact force is too large, which can easily damage the anchor itself.

[0015] 2. After pushing the U-shaped frame to rotate along the fan-shaped groove to the appropriate position, the staff releases the pressure on the pressing plate, and the reaction force of the torsion spring will push the sliding clamp column to insert into the sliding block at the corresponding position for fixation, so that the upper clamping plate and the lower clamping plate rotate to drive the worn brake plate to fit closely with the brake disc. The appropriate clamping distance can ensure that the brake plate is in close contact with the brake disc, so that the anchor chain roller can decelerate or stop more quickly and forcefully during braking, avoiding errors that lead to the inability to accurately control the speed of the anchor chain roller.

[0016] 3. By pushing the push rod to move, the coupling wheels at both ends of the docking drum can be controlled to engage with the coupling disc or coupler respectively, driving the rotating cam or brake disc to rotate, and the equipment drive can be automatically switched. The compressed reset spring will push the protruding direction of the rotating cam to the other direction under the reaction force, so that the brake plates on both sides are opened and no longer fit the brake disc. The automatic cancellation of the clamping function eliminates this step, greatly improving work efficiency, reducing operational errors caused by human factors, and improving operation reliability.

[0026] One end of the upper clamping plate 204 and the lower clamping plate 205 are both rotatably connected to a rotating pulley 214, and the rotating pulley 214 is slidably connected in the limiting slide groove 213. The upper part of the limiting displacement plate 212 is symmetrically provided with a fan-shaped groove 215, and the fan-shaped groove 215 is arranged at one end of the limiting slide groove 213. A U-shaped frame 216 is rotatably connected in the fan-shaped groove 215, and a sliding block 217 is arranged at one end of the fan-shaped groove 215, and the sliding block 217 is opened along the arc at one end of the fan-shaped groove 215.

[0027] One end of the U-shaped frame 216 is fixedly connected to a sliding block 217, one end of the sliding block 217 is connected to a pressing plate 218 by a torsion spring, the lower surface of the pressing plate 218 is fixedly connected to a sliding clamping column 219, the sliding clamping column 219 is slidably connected in the sliding block 217, a reset spring 220 is fixedly installed on one side of the displacement limiting plate 212, one end of the reset spring 220 is fixedly installed on a limiting frame 221, and the bottom end of the limiting frame 221 is fixedly connected to the inner wall of the anchor machine mounting frame 100.

[0028] The fixing assembly includes a knob 222 arranged on one side of the anchor machine mounting frame 100, one end of the knob 222 is fixedly connected to a threaded sleeve 223, the threaded sleeve 223 is rotatably connected to the anchor machine mounting frame 100, one end of the threaded sleeve 223 is threaded with a screw rod 224, one end of the screw rod 224 is fixedly connected to a push plate 225, the push plate 225 abuts against one side of the limit displacement plate 212, one side of the limit displacement plate 212 is fixedly connected to a limit sliding column 226, and the limit sliding column 226 is slidably connected to the push plate 225.

[0029] Specifically, by rotating the cam 202, the sliding plate 211 on the lower surface of the limit displacement plate 212 is pushed to slide along the movable slide groove 210. While sliding, the limit displacement plate 212 will squeeze the reset spring piece 220 between the limit displacement plate 212 and the limit frame 221, and the limit sliding column 226 on one side of the limit displacement plate 212 will slide along the push plate 225, so that the rotating pulley 214 at one end of the upper clamping plate 204 and the lower clamping plate 205 will slide along the limit sliding groove 213 into the U-shaped frame 216. When the rotating pulley 214 slides along the inclined slide from the horizontal slide of the limit sliding groove 213, the upper clamping plate 204 and the lower clamping plate 205 are gradually driven to rotate around the fixed frame 203, and at the same time, the brake plate 206 at one end of the upper clamping plate 204 and the lower clamping plate 205 will gradually The brake disc 208 in the middle is clamped, so that the rotation speed of the anchor chain roller on one side of the brake disc 208 is reduced accordingly. When the protruding direction of the rotating cam 202 does not contact one side of the displacement limiting plate 212, the compressed reset spring piece 220 will push the displacement limiting plate 212 to slide along the moving slide groove 210. On the contrary, when the anchor reaches the predetermined position on the seabed, the staff drives the threaded sleeve 223 to rotate on the anchor machine mounting frame 100 by turning the knob 222, so that the screw rod 224 in the threaded sleeve 223 gradually extends out, and the push plate 225 at one end of the screw rod 224 pushes the displacement limiting plate 212 to slide, so that the upper clamping plate 204 and the lower clamping plate 205 drive the brake plate 206 to rotate to clamp the brake disc 208, fix the position of the displacement limiting plate 212, and stop the anchor chain roller on one side of the brake disc 208; Furthermore, when the brake plate 206 and the brake disc 208 are worn out during use, the staff presses the pressing plate 218 on the limit displacement plate 212 to rotate the pressing plate 218 along one end of the sliding block 217, and moves the sliding clamping column 219 at one end of the pressing plate 218 out of the sliding block 217. After pushing the U-shaped frame 216 to rotate to a suitable position along the fan-shaped groove 215, the staff releases the pressure on the pressing plate 218, and the reaction force of the torsion spring will push the sliding clamping column 219 to be inserted into the sliding block 217 at the corresponding position for fixation, so that the angular position of the U-shaped frame 216 in the fan-shaped groove 215 is fixed, so that the upper clamping plate 204 and the lower clamping plate 205 can rotate to drive the worn brake plate 206 to keep it tightly in contact with the brake disc 208, thereby avoiding errors that may cause the inability to accurately control the speed of the anchor chain roller.

[0031] A push rod 312 is fixedly connected to one side of the clamping frame 311, an L-shaped mounting plate 313 is fixedly connected to the upper surface of the anchor machine mounting frame 100, a sliding groove 314 is opened on the L-shaped mounting plate 313, and the push rod 312 is slidably connected in the sliding groove 314, and coupling wheels 315 are fixedly connected to both ends of the docking rotating cylinder 309, and limiting columns 316 are fixedly connected to both ends of the docking rotating cylinder 309.

[0032] A coupling disk 317 is provided at one end of the docking rotating cylinder 309, and a rotating rod 318 is fixedly connected to one side of the coupling disk 317, and one end of the rotating rod 318 is fixedly connected to the driving gear 302.

When it is necessary to drive the rotating cam 202 at one end to rotate, the staff pushes the push rod 312 to move along the sliding groove 314 to one end. During the movement, the push rod 31 2 will come into contact with the inclined surface at the bottom end of the elastic inclined block 322. As the push rod 312 continues to move, it will push the elastic inclined block 322 to rise. After passing through, the push rod 312 will be limited by the elastic inclined block 322 and cannot move. While the clamping frame 311 drives the docking drum 309 to move, the gear plate 306 will limit the sliding gear 307 above, so that the limiting slider 308 slides to one end along the adjusting slot 310, and the limiting columns 316 at both ends of the docking drum 309 slide in the placement slot 321. The coupling at one end of the docking drum 309 The coupling wheel 315 will mesh with the coupling disc 317 at one end of the rotating rod 318, and the gear disc 306 will be driven to rotate through the output end of the motor 301, so that the sliding gear 307 meshing above the gear disc 306 drives the docking rotating drum 309 to rotate, and the rotating cam 202 at one end of the rotating rod 318 is driven to rotate through the meshing of the coupling wheel 315 and the coupling disc 317, and the displacement limiting plate 212 is intermittently pushed to slide, so that the anchor chain roller rotates at a uniform speed to release the anchor. When it is necessary to retrieve the anchor, the staff pushes the push rod 312 along the sliding groove 3 14 moves to one end, and the steps are opposite to those of the above, driving the coupling wheel 315 at the other end of the docking rotating drum 309 to engage with the coupler 319 at one end of the rotating shaft 320. At the same time, the compressed reset spring piece 220 will push the limit displacement plate 212 to slide and reset under the reaction force, and push the protruding direction of the rotating cam 202 to the other direction, so that the brake plates 206 on both sides are opened and no longer fit the brake disc 208, and the brake disc 208 on the mounting bracket 207 is driven to rotate through the rotating shaft 320, so that the anchor chain roller rotates to retract the anchor.

The rotation of the driven gear 303 will simultaneously drive the rotating cam 202 on one side of the fixed bracket 201 to rotate, and intermittently push the limiting assembly to slide on the anchor windlass mounting frame 100. While the limiting assembly slides along the inner wall of the anchor windlass mounting frame 100, it will simultaneously drive the upper clamping plate 204 and the lower clamping plate 205 to rotate along the fixed frame 203 to clamp the brake disc 208 on one side of the anchor chain roller.
